Arousal parasomnias including night terrors, sleep walking and confusional arousals are behaviors that arise out of deep non-REM sleep (stages 3 & 4), typically in the first third of the nights sleep. Arousal parasomnias are common and can be regarded as part of normal sleep unless the behavior produces disruption to the individual or their family. An arousal can vary from sitting up in bed and making a few minor vocalisations and then lying down again to a night terror in which the individual rouses, may walk, talk, appear to be agitated or frightened, shout and scream and fail to recognize family members. These events may be misdiagnosed as temporal lobe seizures however confusional arousals and night terrors are typically longer and are only broadly stereotyped. The individual throughout this behavior is still sleeping with slow waves seen on the EEG. Arousal parasomnias tend to occur more at times of anxiety and psychological stress. There is typically no recollection of the arousal, however dramatic it is. There is often a family history suggesting a genetic predisposition. If arousals are occurring more than once a night or every night then the differential of nocturnal frontal lobe seizures should be considered. Video, including the onset of the event, is usually the most useful investigation as ictal EEG is often obscured by movement artefact and deep frontal lobe discharges may not be visible on surface EEG (the ictal EEG may be normal). Video of multiple events will reveal the stereotyped nature of epileptic seizures. History from the individual may reveal retained awareness during the event in frontal lobe seizures. |
